From The Raid: Berandal, there is a scene where Bunawar investigates the aftermath of the first film, while investigating, Reza is seen in the courtroom with a man, Reza tells him that he'll continue to investigate the aftermath of the mess. Later on, after discovering the death of Andi, Rama agrees to go undercover and take out Reza's corruption dealings, as well as his crooked plans to bring both Bangun and Goto out of the seat for good, Bunawar urges Rama that in order to stop Reza and his organization, Rama would need the names that puts Reza's hands in Bangun's pockets and that if this doesn't end quickly then Reza and his crooks would come after Rama and kill him and his family.

Later on a man called Bejo would discover this and, planning to take care of Bangun personally, invites Bangun's son, Uco, to have dinner with him, it is later revealed that Bejo wants to bring Bangun to an end so that Uco can claim what he wants, the reason for this is that Bejo is revealed to be an ally of Reza, and while Uco handles Bangun, Bejo can help Reza bring down Goto and take what's theirs. a while later as the plan works, Rama has a taxi ride, but before the taxi man can drive anywhere, a group of attackers surprise Rama and nearly kill him, with their knives even barley missing, but Rama escapes before being chase down by the attackers, this forces Rama to stop and kill all the attackers, while scaring and killing the last one, Rama is horrified and shocked to learn that the men who tried to kill him were police, meaning that the attackers were led by Reza, an injured Rama would later call Bunawar and demands to know why the police are attacking him, Bunawar tells Rama that things are going pretty territorial and that Reza and his men and starting to get ready to bring Goto down, Rama then demands to know what he has not witness from Reza, Rama thought that it was murder, extortion or bribery but it is revealed to be corruption, Rama is shocked to learn that he was never really on course to investigate Bangun or Goto, Bunawar tells him that he and his division just wanted to know how much Reza and his crooks were paying for, like Reza did to Tama before betraying Wahyu.

A while later, unseen in the movie, Reza betrays Goto as around the same time, Bangun would later be killed by Bejo, unsure to Reza for a little, Uco was the one who killed him, and after Rama's escape, Goto would eventually discover Bangun's death but becomes even more concerned when he finds out that Reza betrayed him, in a relation, Goto demands to go to war, after finding out that Uco killed Bangun and Reza is meeting up with Bejo (and Uco) to discuss some terms on a new interested deal, Goto makes a decision, he demands that Bejo's gang, including Bejo and even Uco, all get killed, in an attempt to avenge Bangun, However, he also wants to avenge himself when he demands the same thing to Reza and his friends (with Goto finally having enough of Reza and his schemes of his corruption) his son, Keiichi, becomes shocked with his father's plan against Reza but Goto warns him that Reza and his friends are no longer cops anymore, they are in his world now.

A while later, following the death of Eka, and Bunawar's investigation about Bangun's death, he reveals to Rama that Reza is meeting up with Bejo and Uco to discuss some interests in wiping out Goto's land. During the meeting, Reza talks to Bejo on how they plan to get rid of Goto and his syndicate before taking the territory. Reza attempts to get Uco's attention before he notices Bejo receiving some news. Reza asks him if he is ok and Bejo tells him to have no worries. A while later, everything changes when Rama suddenly bursts him and kills all of Bejo's security. Bejo attempts to throw a gun to Reza, who is prepared but is shocked when Uco grabs it instead, he points it at Reza, who eventually realizes too late that Uco betrayed him, before he can react, Uco shoots Reza, killing him. Though he would not be the only one who is betrayed and killed, Uco soon did the same to Bejo, by wounding him before killing him, though Rama unexpectedly avenges the two by killing Uco.

Rama then leaves Reza's dead body, along with Uco's Bejo's and his own henchmen before being confronted by Keiichi and Goto's men, Rama reveals that he did the job for them and that everyone, including Reza is dead, Bunawar also discovers this for a unknown reason.

Though his personal friend Bejo was thought to be the main antagonist in the sequel, due to his over ambition plots against the underworld of Jakarta. Reza is soon revealed to be the main antagonist of the film, despite having two appearances in the film. Not only did he cause the corruption and also the war, This also forced the film's protagonist Rama to go undercover to face the underworld.

In reality. Though he got himself in the crossfire with Bangun, Goto, Uco and Bejo. It turns out thatRama's true enemy and target is in fact Reza himself. This might be because Bunawar warned him that if Rama doesn't do any of this, Reza would be the one who has his family and himself hunted down and killed.

Also, while Rama serves as the franchise's protagonist, Reza is so far the franchise's antagonist, Despite his death and only two appearence in the sequel whilst making no appearances in the prequel.

Reza is the 2nd highest person who betrayed his own associates or friends. He betrayed Wahyu, Bangun, Goto and Uco (who caused the most betrayals, while his partner Bejo is only just behind him).

Reza also has the highest count of enemies, with all but Bejo and Tama Riyadi, as his only key players and friends.
